I haven't found anything good enough for this. Ideally it should be like Pinterest (or maybe Instagram) for text, an unlimited canvas of text previews (masonry.js style or stacked design). A search function would also be useful.

I was thinking that this description is close to a blog but I'd like it to be optimized for displaying a lot of different snippets (as in Pinterest and giving the choice to the user to "peruse" through the entries quickly) but clicking on an entry should result in expanding into full content (again like Pinterest).

A Hugo blog offers a clean view of the titles (one after the other) but no preview of the actual content. Wordpress is optimized for only a posts per page. On the other end something like Bret Victor's quote page is too simple and doesn't offer the "read more" feature: http://worrydream.com/quotes/

Anyone has seen anything out there that matches my needs? I don't mind paid services.
